Description

Technical Field

[0001] The present invention relates to the field of smart home technology, and specifically provides a calibration method for washing equipment. Background Art

[0002] Washing machines are common household laundry equipment. According to the washing method, washing machines can be roughly divided into pulsator washing machines and drum washing machines. Taking pulsator washing machines as an example, in order to meet the needs of users, pulsator washing machines are equipped with a weight detection module. When the user puts the clothes into the inner drum, the weight detection module performs fuzzy weighing on the clothes, and determines the water volume, such as the washing water volume and the rinsing water volume, based on the results of the fuzzy weighing.

[0003] However, after the washing machine has been used for a long time, its parts will age. For example, the tightness of the belt will change due to reaching its fatigue limit. For a fixed-frequency washing machine, when the belt is too tight, the fuzzy pulse value will be too small and the fuzzy weighing result will be too large; when the belt is too loose, the fuzzy pulse value will be too large and the fuzzy weighing result will be too small. In either case, the fuzzy weighing result will be inaccurate. Since the corresponding relationship between the fuzzy weighing result and the water volume is fixed, the water volume determined according to the fuzzy weighing result will be too high or too low, which will either fail to meet normal washing needs or cause a waste of water resources, affecting the user experience.

[0004] Therefore, the art needs a new calibration method for washing equipment to solve the above problems. Summary of the invention

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the correspondence between the result of fuzzy weighing and the water volume of the existing washing equipment is fixed, which leads to inaccurate water volume determined according to the result of fuzzy weighing, the present invention provides a calibration method for washing equipment, which comprises the following steps: the calibration method comprises the following steps: the washing equipment receives a calibration control instruction; the washing equipment enters a calibration mode based on the calibration control instruction; after the washing equipment enters the calibration mode, the washing equipment receives a water level adjustment instruction; the washing equipment selectively adjusts the water volume corresponding to each current gear position based on the water level adjustment instruction.

[0006] In the preferred technical scheme of the above-mentioned calibration method, the step of "the washing equipment selectively adjusts the water volume corresponding to each current gear position based on the water level adjustment instruction" specifically includes: the washing equipment determines the corresponding adjusted water volume according to the water level adjustment instruction; the washing equipment selectively adjusts the water volume corresponding to each current gear position according to the adjusted water volume.

[0007] In the preferred technical scheme of the above-mentioned calibration method, the step of "the washing device selectively adjusts the water volume corresponding to each current gear position according to the adjusted water volume" specifically includes: the washing device determines the target water volume according to the adjusted water volume and the water volume corresponding to each current gear position; the washing device compares the target water volume with the maximum water volume and the minimum water volume respectively; based on the comparison result, the washing device selectively adjusts the water volume corresponding to each current gear position to the target water volume.

[0008] In the preferred technical scheme of the above-mentioned calibration method, the step of "based on the comparison result, the washing device selectively adjusts the water volume corresponding to each current gear position to the target water volume" specifically includes: if the target water volume is greater than the minimum water volume but less than the maximum water volume, then the water volume corresponding to each current gear position is adjusted to the target water volume.

[0009] In the preferred technical scheme of the above-mentioned calibration method, the step of "based on the comparison result, the washing device selectively adjusts the water volume corresponding to each current gear position to the target water volume" also includes: if the target water volume is less than or equal to the minimum water volume, then the water volume corresponding to each current gear position is adjusted to the minimum water volume.

[0010] In the preferred technical scheme of the above-mentioned calibration method, the step of "based on the comparison result, the washing device selectively adjusts the water volume corresponding to each current gear position to the target water volume" also includes: if the target water volume is greater than or equal to the maximum water volume, then the water volume corresponding to each current gear position is adjusted to the maximum water volume.

[0011] In the preferred technical solution of the above calibration method, after "the washing device adjusts the current water volume corresponding to each gear position based on the water level adjustment instruction", the calibration method also includes: the washing device stores the adjusted water volume corresponding to each gear position.

[0012] In addition, the present invention also provides a calibration method for a washing device, wherein the washing device includes a conveyor belt and a tension detection component arranged on the conveyor belt, and the tension detection component is used to detect the tension of the conveyor belt; the calibration method includes the following steps: detecting the tension by the tension detection component; judging whether it is necessary to calibrate the water volume corresponding to each current gear position of the washing device according to the tension; if it is determined that it is necessary to calibrate the water volume corresponding to each current gear position, making the washing device enter a calibration mode; after the washing device enters the calibration mode, adjusting the water volume corresponding to each current gear position according to the tension.

[0013] In the preferred technical scheme of the above-mentioned calibration method, the step of "determining whether it is necessary to calibrate the water volume corresponding to each current gear position of the washing device based on the tension" specifically includes: determining whether the tension is within a preset tension range; if the tension is within the preset tension range, determining that it is not necessary to calibrate the water volume corresponding to each current gear position; and / or if the tension is not within the preset tension range, determining that it is necessary to calibrate the water volume corresponding to each current gear position.

[0014] In the preferred technical scheme of the above-mentioned calibration method, the step of "adjusting the water volume corresponding to each current gear position according to the tension" specifically includes: calculating the difference between the tension and the preset tension threshold; judging the preset deviation range in which the difference lies; determining the adjusted water volume corresponding to the water volume corresponding to each current gear position according to the judgment result; determining the target water volume according to the adjusted water volume and the water volume corresponding to each current gear position; comparing the target water volume with the maximum water volume and the minimum water volume respectively; and selectively adjusting the water volume corresponding to each current gear position to the target water volume according to the comparison result.

[0015] It can be understood by those skilled in the art that, in the preferred technical solution of the calibration method of the present invention, the washing machine receives a calibration control instruction; the washing machine enters a calibration mode based on the calibration control instruction; after the washing machine enters the calibration mode, the washing machine receives a water level adjustment instruction; and the washing machine selectively adjusts the amount of water corresponding to each current gear based on the water level adjustment instruction.

[0016] Compared with the technical solution in the prior art in which the correspondence between the result of fuzzy weighing and the amount of water in the washing machine is fixed, the washing machine of the present invention can enter the calibration mode based on the calibration control instruction, and selectively adjust the amount of water corresponding to each current gear of the washing machine based on the water level adjustment instruction, thereby adjusting the correspondence between the result of fuzzy weighing and the amount of water. Regardless of whether the result of fuzzy weighing is too large or too small, the amount of water determined by the adjusted correspondence can match the actual weight of the clothes, which not only meets normal washing needs but also does not cause waste of water resources, thereby achieving the purpose of providing the most reasonable amount of water for the operation of the washing machine, thereby improving user experience.

[0017] Furthermore, the washing machine determines the corresponding adjusted water volume according to the water level adjustment instruction, and can accurately determine the adjustment range of the water volume corresponding to each current gear, thereby accurately calibrating the water volume corresponding to each current gear; the washing machine selectively adjusts the water volume corresponding to each current gear according to the adjusted water volume, thereby adjusting the correspondence between the fuzzy weighing result and the water volume, so that the water volume determined by the fuzzy weighing result can match the actual weight of the clothes, thereby being able to accurately determine the actual water intake volume, further improving the user experience.

[0018] In addition, the present invention also provides a calibration method for a washing machine, which determines whether it is necessary to calibrate the water volume corresponding to each current gear of the washing machine according to the tension of the conveyor belt, and can timely and accurately determine whether it is necessary to calibrate the water volume corresponding to each current gear, thereby avoiding the situation where the belt is loose and the result of fuzzy weighing is inaccurate, and the washing machine still recommends the water level according to the corresponding relationship between the existing fuzzy weighing result and the water volume; and after the washing machine enters the calibration mode, the water volume corresponding to each current gear is adjusted according to the tension of the conveyor belt, so that the adjusted water volume corresponding to each gear matches the current tension of the conveyor belt, and because the current tension of the conveyor belt corresponds to the result of fuzzy weighing, the corresponding relationship between the result of fuzzy weighing and the water volume is adjusted accordingly, so that the water volume determined by the adjusted corresponding relationship can match the actual weight of the clothes, which not only meets the normal washing needs, but also does not cause waste of water resources, and achieves the purpose of providing the most reasonable water level for the operation of the washing machine, thereby improving the user experience.

[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the present invention is described in conjunction with a washing machine, the technical solution of the present invention is not limited thereto, and the calibration method can obviously also be applied to other washing equipment such as a washer-dryer, and such a change does not deviate from the principle and scope of the present invention.

[0029] It should be noted that, in the description of the present invention, the terms "first", "second", "third", "fourth" and "fifth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] Based on the technical problems raised in the background technology, the present invention provides a calibration method for a washing machine, which aims to enter a calibration mode based on a calibration control instruction, and selectively adjust the amount of water corresponding to each current gear of the washing machine based on a water level adjustment instruction, thereby adjusting the correspondence between the result of fuzzy weighing and the amount of water.

[0031] See first Figures 1 to 5 , a first embodiment of the calibration method of the present invention is described. Figure 1 is a main flow chart of the calibration method of the first embodiment of the present invention; Figure 2 is a flow chart of a calibration method for selectively adjusting the water volume corresponding to each current gear position based on a water level adjustment instruction according to a first embodiment of the present invention; Figure 3 is a flow chart of a calibration method for selectively adjusting the water volume corresponding to each current gear position according to the adjustment of the water volume according to the first embodiment of the present invention; Figure 4 It is a flow chart of a calibration method for selectively adjusting the water volume corresponding to each current gear position to the target water volume according to the comparison result in the first embodiment of the present invention.

[0032] Embodiment 1

[0033] like Figure 1 As shown, the calibration method of the present invention comprises the following steps:

[0034] S100, the washing machine receives a calibration control instruction;

[0035] S200, the washing machine enters a calibration mode based on a calibration control instruction;

[0036] S300, after the washing machine enters the calibration mode, the washing machine receives a water level adjustment instruction;

[0037] S400: The washing machine selectively adjusts the amount of water corresponding to each current gear position based on the water level adjustment instruction.

[0038] The calibration control instruction is an instruction for controlling the washing machine to enter a calibration mode.

[0039] The calibration mode is a mode for calibrating the amount of water corresponding to each current gear position.

[0040] In step S100, the washing machine is provided with function keys for inputting calibration control instructions, and the function keys include a power key, a selection key, and a water volume key. Preferably, the specific manner in which the washing machine receives the calibration control instruction may be: determining whether the function key is operated; if the function key is operated, it means that the user simultaneously operates the power key, the selection key, and the water volume key, that is, it can be considered that the user inputs the instruction to enter the calibration mode, and then it is determined that the washing machine receives the calibration control instruction; if the function key is not operated, it means that the user does not simultaneously operate the power key, the selection key, and the water volume key, that is, only operates any one or any two of the power key, the selection key, and the water volume key. In either case, it can be considered that the user does not input the instruction to enter the calibration mode, and then it is determined that the washing machine receives the calibration control instruction.

[0041] Furthermore, when the power button is in the off state, the user operates the power button, the selection button and the water volume button at the same time, which can be regarded as inputting the instruction to enter the calibration mode.

[0042] It should be noted that the function keys listed above are only exemplary and not restrictive. The function keys may also include only a power button, a selection key or a water level key, or only any two of the power button, the selection key and the water level key. The function keys may also be other operation keys provided on the washing machine, such as a child lock key, a start key, etc. Those skilled in the art may flexibly adjust and set the types and combinations of function keys for inputting calibration control instructions according to actual usage requirements, and the present invention does not impose any limitations on this.

[0043] Of course, the method for receiving the calibration control instruction is not limited to the methods listed above. A communication module may also be set on the washing machine, and the washing machine communicates with the server through the communication module, and the washing machine can receive the calibration control instruction from the server; or, the washing machine communicates with the smart terminal through the communication module, and the washing machine can receive the calibration control instruction from the smart terminal, wherein the smart terminal can be a mobile phone, a computer, a wearable device, a smart mobile device, a virtual reality device, etc., or any combination thereof. No matter which method is adopted, as long as the washing machine can receive the calibration control instruction, the present invention does not impose any restrictions on this.

[0044] In step S300, the specific way for the washing machine to receive the water level adjustment instruction can be: receiving the water level adjustment instruction input through other function keys such as the water volume key; or the washing machine can receive the water level adjustment instruction from the server; or the washing machine can receive the water level adjustment instruction from the smart terminal. No matter which method is adopted, as long as the washing machine can receive the water level adjustment instruction, the present invention does not impose any restrictions on this.

[0045] like Figure 2 As shown, in step S400, the step of "the washing machine selectively adjusts the water volume corresponding to each current gear position based on the water level adjustment instruction" specifically includes:

[0046] S411, the washing machine determines the corresponding adjusted water volume according to the water level adjustment instruction;

[0047] S412: The washing machine selectively adjusts the amount of water corresponding to each current gear position according to the adjusted water amount.

[0048] In step S411, the washing machine determines the corresponding adjusted water volume according to the water level adjustment instruction, and can accurately determine the adjustment range of the water volume corresponding to each current gear, thereby accurately calibrating the water volume corresponding to each current gear.

[0049] For example, the water level adjustment instruction input by the user through the water volume key can be to adjust the water volume of other gears such as 0, 1, 2, 3, and -1, among which 0 means no adjustment of the water volume, and the adjusted water volume corresponding to 0 is the water volume corresponding to each current gear; 1 means an increase of 3L of water; 2 means an increase of 6L of water; 3 means an increase of 9L of water; -1 means a decrease of 3L of water, as shown in Table 1.

[0050] Table 1. Water volume adjustment comparison table

[0051]

[0052] like Figure 3 As shown, in step S412, the step of "the washing machine selectively adjusts the water volume corresponding to each current gear according to the adjusted water volume" specifically includes:

[0053] S421, the washing machine determines the target water volume according to the adjusted water volume and the water volume corresponding to each current gear position;

[0054] S422, the washing machine compares the target water volume with the maximum water volume and the minimum water volume respectively;

[0055] S423. According to the comparison result, the washing machine selectively adjusts the water volume corresponding to each current gear position to the target water volume.

[0056] In step S421, the washing machine determines the target water volume according to the adjusted water volume and the water volume corresponding to each current gear. For example, as shown in Table 1, the washing machine currently has five water volumes, namely 24L, 32L, 40L, 51L and 55L, wherein 24L is the lowest water volume of the washing machine and 55L is the highest water volume of the washing machine; if the water level adjustment instruction input by the user through the water volume key in step S411 is to adjust the water volume of gear 1, gear 1 means to increase the water volume by 3L, then the five water volumes of the washing machine are increased by 3L of water respectively, and accordingly, the target water volumes corresponding to the five water volumes of the washing machine are 27L, 35L, 43L, 54L and 58L respectively.

[0057] For example, in step S411, the water level adjustment instruction input by the user through the water level button is to adjust the water volume to -1 level, and -1 level means reducing 3L of water. Then the five water levels will be reduced by 3L of water respectively. Accordingly, the target water volumes corresponding to the five water levels of the washing machine are 21L, 29L, 37L, 48L and 52L respectively.

[0058] In step S422, since the adjusted water volume may be greater than the maximum water volume of the washing machine, for example, in step S421, after adjusting the water volume to level 1, the target water volume corresponding to the current 55L water volume is 58L, which is greater than the maximum water volume (i.e., 55L); the adjusted water volume may also be less than the minimum water volume of the washing machine, for example, in step S421, after adjusting the water volume to level -1, the target water volume corresponding to the current 24L water volume is 21L water, which is less than the minimum water volume (i.e., 24L). In either case, the water volume setting requirement of the washing machine cannot be met. Therefore, it is necessary to compare the target water volume with the maximum water volume and the minimum water volume respectively, and based on the comparison results, the washing machine selectively adjusts the water volume corresponding to each current gear to the target water volume.

[0059] like Figure 4 As shown, in step S423, the step of "according to the comparison result, the washing machine selectively adjusts the water volume corresponding to each current gear to the target water volume" specifically includes:

[0060] S431, if the target water volume is greater than the minimum water volume but less than the maximum water volume, adjusting the water volume corresponding to each current gear position to the target water volume;

[0061] S432: If the target water volume is less than or equal to the minimum water volume, the water volume corresponding to each current gear position is adjusted to the minimum water volume;

[0062] S433: If the target water volume is greater than or equal to the maximum water volume, the water volume corresponding to each current gear position is adjusted to the maximum water volume.

[0063] In step S431, if the target water volume is greater than the minimum water volume but less than the maximum water volume, for example, the minimum water volume of the washing machine is 24L, and the maximum water volume of the washing machine is 55L, in step S421, after adjusting the water volume at level 1, the target water volumes corresponding to the current water volumes of 24L, 32L, 40L and 51L are 27L, 35L, 43L and 54L respectively, which are greater than the minimum water volume but less than the maximum water volume, and are within the normal water volume range of the washing machine. The current water volume of 24L is adjusted to 27L, the current water volume of 32L is adjusted to 35L, the current water volume of 40L is adjusted to 43L, and the current water volume of 51L is adjusted to 54L, as shown in Table 1.

[0064] For another example, in step S421, after adjusting the water volume at -1 gear, the target water volumes corresponding to the current 32L, 40L, 51L and 55L water volumes are 29L, 37L, 48L and 52L respectively, which are all greater than the minimum water volume but less than the maximum water volume, and are within the normal water volume range of the washing machine. The current 32L water volume is adjusted to 29L, the current 40L water volume is adjusted to 37L, the current 51L water volume is adjusted to 48L, and the current 55L water volume is adjusted to 52L, as shown in Table 1.

[0065] In step S432, if the target water volume is less than or equal to the minimum water volume, for example, the minimum water volume of the washing machine is 24L, in step S421, after adjusting the water volume at -1 level, the target water volume corresponding to the current 24L water volume is 21L, which is less than the minimum water volume. The water intake at 21L cannot meet the minimum water volume requirement of the washing machine, and the current 24L water volume is maintained at 24L without adjusting the water volume, as shown in Table 1.

[0066] In step S433, if the target water volume is greater than or equal to the maximum water volume, for example, the maximum water volume of the washing machine is 55L, in step S421, after adjusting the water volume at level 1, the target water volume corresponding to the current 55L water volume is 58L, which is greater than the maximum water volume and exceeds the maximum water volume of the washing machine. The water intake at 58L cannot meet the maximum water volume requirement of the washing machine, and the current 55L water volume is maintained at 55L without adjusting the water volume, as shown in Table 1.

[0067] It should be noted that the adjustment gears, the number of adjustment gears, the adjusted water volume corresponding to each gear, the target water volume, the adjusted water volume, the number of current gears and the water volume corresponding to each current gear listed above are only exemplary and not restrictive. Technical personnel in this field can flexibly adjust and set the adjustment gears, the number of adjustment gears, the adjusted water volume corresponding to each gear, the target water volume, the adjusted water volume, the number of current gears and the water volume corresponding to each current gear according to the actual fuzzy weighing results, the actual weight of the clothes and the water volume corresponding to each current gear. The present invention does not impose any restrictions on this.

[0068] It should also be noted that in the above process, steps S431 to S433 have no order of precedence but are parallel and are only related to the comparison results of the target water volume with the maximum water volume and the minimum water volume respectively. The corresponding steps can be executed according to different comparison results.

[0069] Although not shown in the figure, after step S400, the calibration method further includes:

[0070] The washing machine stores the adjusted water volume corresponding to each gear.

[0071] Preferably, the washing machine is provided with a storage module. When the washing machine adjusts the water volume corresponding to each gear, the storage module immediately stores the adjusted water volume corresponding to each gear; the adjusted water volume corresponding to each gear may also be stored after the washing machine adjusts the water volume corresponding to each gear and after a preset time interval, for example, the adjusted water volume corresponding to each gear may be stored after 5s, 10s, 15s or 20s; the adjusted water volume corresponding to each gear may also be stored after the washing machine is turned off. Those skilled in the art may flexibly adjust and set the timing of storing the adjusted water volume corresponding to each gear according to actual storage needs.

[0072] See below Figures 5 to 7 , a second embodiment of the calibration method of the present invention is described. Figure 5 is a main flow chart of the calibration method of the second embodiment of the present invention; Figure 6 is a main flow chart of a calibration method for determining whether it is necessary to calibrate the water volume corresponding to each current gear position of a washing machine according to a second embodiment of the present invention; Figure 7 It is a flow chart of a calibration method for adjusting the amount of water corresponding to each current gear position according to tension in the second embodiment of the present invention.

[0073] Embodiment 2

[0074] The washing machine of the present invention comprises a conveyor belt and a tension detection member arranged on the conveyor belt, wherein the tension detection member is used to detect the tension of the conveyor belt. The tension detection member may be, but is not limited to, a strain gauge and a tension meter. Regardless of the tension detection member, the corresponding specific detection method shall not constitute any limitation to the present invention.

[0075] like Figure 5 As shown, the calibration method includes the following steps:

[0076] S500, detecting tension by a tension detection component;

[0077] S600, judging whether it is necessary to calibrate the water volume corresponding to each current gear position of the washing machine according to the tension;

[0078] S700: if it is determined that the water volume corresponding to each current gear position needs to be calibrated, the washing machine enters a calibration mode;

[0079] S800: After the washing machine enters the calibration mode, the amount of water corresponding to each current gear is adjusted according to the tension.

[0080] The calibration mode is a mode for calibrating the amount of water corresponding to each current gear position.

[0081] By adopting the above method, whether the water volume corresponding to each current gear of the washing machine needs to be calibrated is judged according to the tension of the conveyor belt, and whether the water volume corresponding to each current gear needs to be calibrated can be judged in a timely and accurate manner, thereby avoiding the situation where the belt is loose and the result of fuzzy weighing is inaccurate, and the washing machine still recommends the water level according to the corresponding relationship between the existing fuzzy weighing result and the water volume; and after the washing machine enters the calibration mode, the water volume corresponding to each current gear is adjusted according to the tension of the conveyor belt, so that the water volume corresponding to each adjusted gear matches the current tension of the conveyor belt, and because the current tension of the conveyor belt corresponds to the result of fuzzy weighing, the corresponding relationship between the result of fuzzy weighing and the water volume is adjusted accordingly, so that the water volume determined by the adjusted corresponding relationship can match the actual weight of the clothes, which not only meets the normal washing needs, but also does not cause waste of water resources, and achieves the purpose of providing the most reasonable water level for the operation of the washing machine, thereby improving the user experience.

[0082] like Figure 6 As shown, in step S600, the step of "determining whether it is necessary to calibrate the water volume corresponding to each current gear position of the washing machine according to the tension" specifically includes:

[0083] S611, determining whether the tension is within a preset tension range;

[0084] S612: If the tension is within the preset tension range, it is determined that there is no need to calibrate the water volume corresponding to each current gear position;

[0085] S613: If the tension is not within the preset tension range, it is determined that the water volume corresponding to each current gear position needs to be calibrated.

[0086] In step S612, if the tension is within the preset tension range, for example, the preset tension range is 4N to 7N, and the detected tension is 5N, which is within the preset tension range, it means that the detected tension is within the normal range, the belt is just the right tightness, the result of the fuzzy weighing of the washing machine is accurate, and the amount of water determined by the result of the fuzzy weighing is also accurate. There is no need to calibrate the amount of water corresponding to each current gear position, and it is determined that there is no need to calibrate the amount of water corresponding to each current gear position.

[0087] In step S613, if the tension is not within the preset tension range, for example, the preset tension range is 4N to 7N, and the detected tension is 7.6N, which is not within the preset tension range and is greater than the maximum value of the preset tension range (i.e. 7N), it means that the detected tension is too large, the belt is too loose, the result of the fuzzy weighing of the washing machine is too low, and the water volume determined by the result of the fuzzy weighing is also inaccurate, which is lower than the water volume corresponding to the actual weight of the clothes. The water volume corresponding to each current gear needs to be increased, and it is determined that the water volume corresponding to each current gear needs to be calibrated.

[0088] For example, the preset tension range is 4N to 7N, and the detected tension is 3.2N, which is not within the preset tension range and is less than the minimum value of the preset tension range (i.e. 4N). This indicates that the detected tension is too small, the belt is too tight, and the result of the fuzzy weighing of the washing machine is too high. The water volume determined by the result of the fuzzy weighing is also inaccurate, which is higher than the water volume corresponding to the actual weight of the clothes. The water volume corresponding to each current gear needs to be reduced, and it is determined that the water volume corresponding to each current gear needs to be calibrated.

[0089] It should be noted that, in the above process, step S612 and step S613 have no order of precedence and are parallel, and are only related to the judgment result of whether the tension is within the preset tension range. The corresponding steps can be executed according to different judgment results.

[0090] like Figure 7 As shown, in step S800, the step of "adjusting the water volume corresponding to each current gear position according to the tension" specifically includes:

[0091] S811, calculating the difference between the tension and the preset tension threshold;

[0092] S812, determining the preset deviation range of the difference;

[0093] S813, determining the adjusted water volume corresponding to the water volume corresponding to each current gear position according to the judgment result;

[0094] S814, determining the target water volume according to the adjusted water volume and the water volume corresponding to each current gear position;

[0095] S815, comparing the target water volume with the maximum water volume and the minimum water volume respectively;

[0096] S816. According to the comparison result, selectively adjust the water volume corresponding to each current gear position to the target water volume.

[0097] In step S811, the tension F detected in step S500 is subtracted from the preset tension threshold F0 to obtain a difference ΔF, ie, ΔF=F-F0.

[0098] For example, the preset tension threshold F0 is 5.5N, the detected tension F is 7.6N, and the calculated difference △F is 2.1N, which is greater than 0, indicating that the belt is too loose and the result of the fuzzy weighing of the washing machine is low. It is necessary to increase the amount of water corresponding to the result of the fuzzy weighing.

[0099] For example, the preset tension threshold F0 is 5.5N, the detected tension F is 3.2N, and the calculated difference △F is -2.3N, which is less than 0, indicating that the belt is too tight and the result of the fuzzy weighing of the washing machine is too high. It is necessary to reduce the amount of water corresponding to the result of the fuzzy weighing.

[0100] In step S812 and step S813, in order to determine the specific adjusted water volume corresponding to the water volume corresponding to each current gear position, the difference calculated in step S811 is compared with different preset deviation ranges, the preset deviation range in which the difference lies is determined, and the adjusted water volume corresponding to the water volume corresponding to each current gear position is determined based on the judgment result.

[0101] For example, a washing machine includes five preset deviation ranges, namely, the first preset deviation range -2.5N to -2N, the second preset deviation range -2N to -1.5N, the third preset deviation range -1.5N to 1.5N, the fourth preset deviation range 1.5N to 2N, and the fifth preset deviation range 2N to 2.5N. Taking a fixed-frequency washing machine as an example, when the belt tension is not within the preset tension range, and the tension is less than the minimum value of the preset tension range, the difference between the tension and the preset tension threshold is less than 0, the belt is too tight, and the value of the fuzzy weighing is too large, and it is necessary to reduce the current deviation of each gear. Therefore, the first preset deviation range corresponds to a reduction of 6L of water, and the second preset deviation range corresponds to a reduction of 3L of water; the third preset deviation range corresponds to the preset tension range mentioned above, that is, it corresponds to no adjustment of the water volume; when the belt tension is not within the preset tension range, and the tension is greater than the maximum value of the preset tension range, the difference between the tension and the preset tension threshold is greater than 0, the belt is too loose, and the value of the fuzzy weighing is too small, and the water volume corresponding to each current gear needs to be increased. Therefore, the fourth preset deviation range corresponds to an increase of 3L of water, and the fifth preset deviation range corresponds to an increase of 6L of water.

[0102] It should be noted that for a variable frequency washing machine, the increase or decrease in water volume corresponding to the above five preset deviation ranges can be adjusted and determined according to the changing trend of the fuzzy weighing value corresponding to the changing trend of the tension of the variable frequency washing machine, which will not be elaborated here.

[0103] For example, the difference ΔF calculated in step S811 is 2.1N, which is within the fifth preset deviation range (ie, 2N to 2.5N), that is, the amount of water corresponding to each current gear position needs to be increased by 6L of water.

[0104] For another example, the difference △F calculated in step S811 is -2.3N, which is within the first preset deviation range (ie, -2.5N to -2N), that is, the amount of water corresponding to each current gear position needs to be reduced by 6L of water.

[0105] In step S814, the target water volume is determined based on the adjusted water volume and the water volume corresponding to each current gear. For example, the washing machine currently has five water volume levels, namely 24L, 32L, 40L, 51L and 55L, among which 24L is the lowest water volume of the washing machine and 55L is the highest water volume of the washing machine. The adjusted water volume corresponding to the current water volume corresponding to each gear determined in step S813 is to increase 6L of water. Then the target water volumes corresponding to the five water volume levels of the washing machine are 30L, 38L, 46L, 57L and 61L respectively.

[0106] For example, the adjusted water volume corresponding to each current gear determined in step S813 is 6L less water, then the target water volumes corresponding to the five water levels of the washing machine are 18L, 26L, 34L, 45L and 49L respectively.

[0107] In step S815, since the adjusted water volume may be greater than the maximum water volume of the washing machine, for example, in step S814, after the water volume is increased by 6L, the target water volume corresponding to the current 51L water volume is 57L, and the target water volume corresponding to the current 55L water volume is 61L, both of which are greater than the maximum water volume (i.e., 55L); the adjusted water volume may also be less than the minimum water volume of the washing machine. For example, in step S814, after the water volume is reduced by 6L, the target water volume corresponding to the current 24L water volume is 18L water, which is less than the minimum water volume (i.e., 24L). In either case, the water volume setting of the washing machine cannot be met. Therefore, the target water volume is compared with the maximum water volume and the minimum water volume respectively, and based on the comparison results, the washing machine selectively adjusts the water volume corresponding to each current gear to the target water volume.

[0108] In S816, according to the comparison result, the water volume corresponding to each current gear is selectively adjusted to the target water volume. The specific method is described in the corresponding steps S431 to S433 in the first embodiment, which will not be repeated here. The specific adjustment results are as follows:

[0109] For example, when the difference △F calculated in the judgment step S811 is 2.1N, which is within the fifth preset deviation range, the adjusted water level is: adjust the current 24L water volume to 30L; adjust the current 32L water volume to 38L; adjust the current 40L water volume to 46L; adjust the current 51L water volume to 55L; maintain the current 55L water volume at 55L and do not adjust the water volume.

[0110] For example, when the difference △F calculated in the judgment step S811 is -2.3N, which is within the first preset deviation range, the adjusted water level is: maintain the current 24L water volume at 24L and do not adjust the water volume; adjust the current 32L water volume to 26L; adjust the current 40L water volume to 34L, adjust the current 51L water volume to 45L, and adjust the current 55L water volume to 49L.

[0111] It should be noted that the tension, preset tension range, preset tension threshold, preset deviation range, the number of preset deviation ranges, the adjusted water volume corresponding to each preset deviation range, the target water volume, the adjusted water volume, the number of current gears, and the water volume corresponding to each current gear listed above are merely exemplary and not restrictive. Those skilled in the art can flexibly adjust and set the tension, preset tension range, preset tension threshold, preset deviation range, the number of preset deviation ranges, the adjusted water volume corresponding to each preset deviation range, the target water volume, the adjusted water volume, the number of current gears, and the water volume corresponding to each current gear according to the actual fuzzy weighing results, the actual weight of the clothes, and the water volume corresponding to each current gear. The present invention does not impose any limitations on this.
